Abstract

With eastern Fujian coastal wetlands under the invasion of Spartina alterniflora as the research object and through comparative analysis of soil moisture content,soil porosity and soil bulk density and using the IBM SPSS Statistics 19,the single factor variance analysis(One-way ANOVA)was performed to test the data difference significance.According to the results,the five communities in Xinan town include single dominant community of mangrove forest,single dominant community of Spartina alterniflora,50% autumn mangrove forest,50% Spartina alterniflora mixed community,75% autumn mangrove forest,25% Spartina alterniflora mixed community and 25% autumn mangrove forest,75% Spartina alterniflora mixed community.The soil moisture content of 0~20cm soil depth was significantly different from that in 40~60cm soil depth,but there was no significant difference in soil porosity and soil bulk density of the single dominant community of mangrove forest and single dominant community of Spartina alterniflora.The soil moisture content,soil porosity and soil bulk density were all significantly different in 40~60cm soil depth with 0~20cm soil depth and 20~40cm soil depth of 50% autumn mangrove forest,50% Spartina alterniflora mixed community.The invasion of Spartina alterniflora caused soil bulk density to increase,the soil porosity decrease and the trend of soil moisture content showed different patterns in different Kandelia Candel-Spartina alterniflora mixed communities in eastern Fujian coastal wetlands.

Key words： Spartina alterniflora; mangrove; soil moisture content; soil porosity; soil bulk density; eastern Fujian coastal wetlands
